ELIJAII IIOUGI'I, OF SAGINAW', MIOHIGAN..

HEATER AND VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 569,381, dated October 13, 1896.

Application filed January 8, 1896. Serial No. 574,671. (No model.)

To all whom it may concern.-

Be it known that I, ELIJAH IIOUGH, a citizen of the United States, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented a new and useful Heater and Ventilator; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to the figures of reference marked thereon, which forms a part of this specification.

My invention is a heater and ventilating attachment for stoves; and it consists in the peculiar arrangement, construction, and combination shown and described.

The figure is a vertical section of the de vice as an attachment to a stove.

In the drawing, 1 is the stove; 2, the stovepipe 5 3, a drum or compartment in which the air is heated, and 4. is a cold-air pipe extendin g to or below the base of the stove and entering the bottom of the drum 3.

5 is a draft-flue inside of the cold-air pipe 4, extending from near the bottom thereof upward into the drum or chamber 3, and from thence into the smoke-pipe 2 above the damper 6.

The arrows in the drawing indicate the direction of the draft or air, viz: The draftpipe 5, entering the smoke-pipe 2, which enters a chimney, creates a constant draft from the floor of the room from behind or underneath the stove, carrying the air in it up through the stovepipe into the chimney. This draft will cause a rush of air into the coldair pipe at. The pipe 5 not being large enough to receive all of the air, it will rise in the pipe at in the drum 3 and there become heated and pass out into the room at the top of the drum, thereby assisting in heating the room and causing a constant circulation of the air and consequent ventilation of the room through the draft-pipe 5. It is obvious that this coldair pipe 4 and its draft-pipe 5 may be extended to any other part of the room or house and draw from the room cold air, which, passing through the drum 3, is heated and discharged into the room where the stove is located, the heat from. the stove returning to take the place of the cold air from the room if the door or radiator to that room shall be open. This pipe 4: may also extend to the basement or to the outside of the building and be the means of conveying pure air into the room, Where it will be discharged from the drum 3 after being heated. By this arrangement of the drum and flues I am enabled to get more results from the fuel, as the radiating-surface of the pipe of the drum is continually heating the cold air taken from the floor or other part of the house, and therefore I am not dependent upon the radiatingsurface of the stove.

By locating the damper 6 below the flue 5 I am enabled to shut ofi the draft from the stove and leave the ventilator in use.

I know that it is old to provide means in a stove for taking cold air from the base of the stove or room, passing it up through the stove and around the fire-pot or body of the stove, and discharging it into the room after being heated; but I am not aware that any means have been heretofore provided for ventilating the room through these cold-air fines, as I do by means of the ventilating-flue 5.

Therefore, what I claim as new, and desire to secure by Letters Patent, is

In a heating and ventilating attachment for stoves, the combination with the stovepipe, of a drum surrounding the pipe and having openings above, and the pipe 4 extending from the base of the drum to the floor, whereby the cold air will be drawn from the floor through the pipe 4: and discharged into the ELIJ AH HOUGH.
